Patent CA-2549102-A1 (CA)
Inventor: BECHLER BOYD C
IPC: A45F5/10
Filed: 2006-05-31
Abstract: A resilient clip-on handle for mounting on propane bottles includes a unitary resilient sheet including a base member and backing member mounted contiguous to each other so as to be de-formable to a position substantially orthogonally relative to each other.  The backing member fits through an opening in a valve protecting collar on a propane bottle.  The backing member is sized and shaped so that, when deformed, it may be mounted to lie flush along the underside of a rigid flange extending outwardly from the collar above the opening in the collar. When so deformed, the base and backing members form a common edge therebetween in an interior corner between the base member and backing member. The interior corner snugs against the seam between the flange and the collar. A  distal end of the base member, when mounted on the flange, is coextensive with the distal end of the flange.

Title: The blending of high vapour pressure diluents for reducing the viscosity of heavy oil
Inventor: PERRY GLEN F
IPC: F17D1/16
Filed: 2006-06-16
Abstract: It is postulated that the blending formula for the viscosity of two products such as bitumen and diluent is not a continuous function of the diluent amount, as has been proposed by all theories to date, but is instead a discontinuous series of at least three log-linear functions, each representing a different phase, as the fluid transitions through the three different primary phases;  gas/liquid, liquid/liquid, and solid/liquid. The log viscosity of a blend of a high vapour pressure natural gas liquid (HVP-NGL) and a heavy oil can be expressed as a simple sum of the relative mole weighting of the log viscosities of the two individual materials, as measured between the phase change boundaries. The liquid/liquid phase over the middle range of diluent % mole defines the primary range of utility in pipelines when utilizing heavy oil, as this oil usually requires at least 15 mole % to reduce the viscosity to the specification, and one must avoid asphaltine deposition beyond 85 mole % for operational reasons.  This is based on the observation that sharp discontinuities in viscosity are usually caused by phase changes. Where a phase is constant, the graph of log viscosity vs. blend mole % composition is approximately linear. It is also postulated that this curve fit is similar across a range of diluents from ethane to pentanes and possibly heavier products all the way through to light cycle oil, implying that (say) 50 mole % propane provides a similar viscosity reduction as 50 mole % pentane for any particular oil.
